ATTACHMENT FOR EDGE-SETTIN G MACHINES.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed November 14, 1914. Serial No. 872,070.

To all whom it may concern Be it known that I, RAOUL J. B. MON- CHAMP, asubject of the King of Great Britain, residing at Manchester, NewHampshire, United States of America, have invented certain new anduseful Improvements in Attachments for Edge-Setting Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use thesame.

The invention to be hereinafter described relates to an attachment foredge setting machines. v

In order to more clearly disclose the construction, operation, and useof the inven- I tion, reference should be had to the accompanyingdrawings forming part of the present application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a front View of the device, partly brokenaway to show its interior construction; and Fig. 2 is an underneath Viewpartly broken away.

The main objects of the invention are, to provide a neat, compact,durable, and efficient device for use in connection with edge settingmachines, in the manufacture of shoes and footwear, for burnishingpurposes.

Referring to the drawings in detail, 1 designates a steel head ofcircular cross section, the upper portion of which is of frustoconicalshape. A heavy shank 2 is made integral with the head and is threaded atits upper end, for attaching purposes. The under face of head 1 iscentrally recessed to receive superposed heating coils 8. An opening isprovided through the center of the coils, and a screw 4 is insertedthrough this opening and threaded into a suitable bore in a plug 5centrally located above the heating coils. The coils 3, screw 4, andplug5, are all effectually insulated from each other and from head 1, bythick layers of asbestos cement, or other suitable insulating material.To prevent heating of the coils, they are each halved by a bridge 6 ofasbestos cement. Several layers of mica are placed between the heatingcoils and the removable bottom plate 7, so as to prevent heatingthereof. A sleeve 8, of material of high electrical conductivity, ismounted about the upper portion of screw 4, and effectually insulatedtherefrom by an asbestos sleeve 9. This sleeve is also insulated, at itsupper end, from bottom plate 7 by a thick mica washer 10, and at itslower end, from the head 11 of the screw 4, by a similar washer 12.Sleeve 8 and screw head 11 are each grooved, near their lower ends, toreceive collared connecting members 13 and 14, respectively. Thesemembers are snugly, but not tightly, mounted and are detachablyconnected, by wires 15, to opposite sides of a suitable electricalcircuit. One end of the coils 3 is connected to sleeve 8 by means of awire 16 passed through, the insulation between the coils and plate 7plate 7, and washer 10, and secured to sleeve 8. The other end of thecoils is connected to plug 5, which is of a high electricalconductivity, by wire 17 which passes through bridge 6 and theinsulation about the plug, and is secured thereto. I

When wires 15 are properly connected, the electrical current will entercoils 3 by screw 4 and plug 5 and leave by sleeve 8, or vice versa. Theflow of the electrical current through coils 3 will soon render themvery hot, which will raise the lower portion of head 1 to a hightemperature. The head 1 is provided, with two diametrically opposite,integral, and angularly disposed pins 18, which project beyond its underface. These pins are adapted to fit snugly into the tubular shanks 19 ofproperly shaped burnishing irons 20, the head being properly recessedabout the pins to snugly receive the shanks. By this means, veryintimate contact is established between the irons and the head 1. Tosecure the irons in position, a fiat steel arm 21 is provided. This armhas lateral tabs 22 which straddle each side of head 1 and are pivotallyconnected thereto by screws 28. The upper end of the arm is forcedoutwardly by a pressure coil spring 22*, which has its inner end seatedin a suitable bore in the head and its outer end fitted over a pinintegral with the arm. The lower end of the arm is turned inwardly toform a short cylinder 23 which fits tightly into a semicylindricalgroove 24 adjacent the upper outer edge of the head of the iron 20, whenthe iron is in operative position. By this means, the iron is securelyretained in operative position, but may be quickly and easily mounted,or demounted, as required. As the head 1 heats the heat is transmittedto irons 20, by pins 18, which are quickly raised to the propertemperature for use.

Due to the fact that connecting members 13 and 14: are not tightlymounted about sleeve 8 and screw 4, this device may be revolved, asdesired, without in any way interfering with its connections oroperation, as will be clear from Fig. l of the drawings. In use, thisdevice may be attached, by

means of shank 2, to the ordinary edge settin machine, in place of thesetting tool,

and then may be used in the ordinary It is thought that theconstruction, operation, and use of the invention will be clear from thepreceding detailed description.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of-the invention without in any way departing from thefield and scope of the same, and it is meant to include all such withinthis application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a device of the character described; a head, having its under facerecessed; attaching means integral therewith; heating coils mounted inthe recess of the head and insulated therefrom; means for electricallyconnecting the said coils to an electrical circuit, such means beingarranged to permit revolution of the head; irons carried by the head anddetachably mounted therein; and means for securing the irons inoperative position.

Copies ofthis patent may be obtained for '2. In a device of thecharacter described; a head having its under face recessed; integralattaching means therefor; heating coils mounted in the recess of thesaid head and insulated therefrom and from each other; a plug ofmaterial of high electrical conductivity centrally located above thecoils and electrically connected to one side thereof, and insulatedtherefrom and from the head, and having a centrally screw threaded bore;a plate removably secured on the lower faceof thesaid'head; a screwinserted through the plate and the coils and threaded into the saidplug, the said screw being insulated from the said coils and plate andhaving an annularly grooved head; an .annularly grooved sleeve of highelectrical conductivity mounted about the -:upper portion thereof andinsulated therefrom and from the said plate and electrically connectedto the other side of the said coils; means for connecting the saidsleeve and screw to opposite sides of an electrical circuit, so as topermit revolution of the said sleeve; diametrically-opposite angularlydisposed pins integral with the said head and (projecting beyond thelower face thereof; ironsvadapted to be mounted on the said pins; andmeans for holdingthe irons in po- 8 s'ition, such means being carried:by the said head.

In witness whereof I have hereunto set my hand in the presence of twowitnesses. RAOULJ. B. ,MONGHAMP. Witnesses:
